Need a brain boost? Have a good old yawn.

How many times have you been told that it’s not polite to yawn when people are speaking, or that we shouldn’t be showing he world how bored we are?

That is something that I am pretty sure we have all been told at one time or another the only problem is the opposite maybe the case. In fact yawning apparently helps cool down our brain making it so that they can function better.

This is from a recent study by Andrew Gallup from New York’s University of Binghamton who specializes in yawning (seriously? someone actually specializes in yawning?)

“Our brains are like computers,” says Gallup, who conducted yawning studies in 2007 with his father, Gordon Gallup, of the State University of New York at Albany. “They operate most efficiently when cool. Our research indicates that we yawn in response to increased brain or body temperature.”

Despite a 1987 study that disproved yawning as a response to reduced oxygen levels, the younger Gallup says some people still believe that’s why we yawn. It’s not. In fact, he adds, comparative support shows that yawning provides a means for achieving increased alertness and arousal, especially when changing from one mental state to another (activity to inactivity or sleeping to waking). So, if anything, it’s a mechanism to recharge so you can better absorb information.
